The possibilities of increasing catching efficiency of male Ips typographus L in pheromone traps barriers and in single traps were tested. Pheromone dispensers with different percentages of (4S)‐ cis ‐verbenol (cV) in pheromone mixtures were used. The results show that the different male catching efficiencies of pheromone trap barriers and single traps were related to the different percentages of cV in the pheromone bait. The proportions of males were higher in pheromone trap barriers than in single traps. Thus increasing the catch of males in pheromone trap barriers is possible by using a combination of pheromone traps containing pheromones giving a higher release of cV with others containing pheromones giving a lower release of cV.
